look up "aura interactor" jaycar in Australia sells the drivers for them for about $10 or so (they are like backpack sized sub-sub-sub woofers with weights instead of speakers so that when your computer game/movie makes the explosion/thwack sound the speaker thing "rumbles" "just like you are there" if you believe their literature.) stick a couple of dozen of those on your bed it'll either wake you up by being violently shaken or alternately give you a nice relaxing massage type vibration. Either way you win. Hmmm now you got me thinking ;-> the other cheaper option is go to bed earlier and just get the amount of sleep your body tells you it needs. (a good 14 to 16 hours seems to work for some mammals) hmmm spell check has the word "thwack" in it. Does the fact I find that exciting mean my life is dull? ----- Original Message ----- From: "Peter L.
